New effector conjugates, methods for their preparation and their pharmaceutical use

ABSTRACT

Conjugates of epothilones and epothilone derivatives (as effectors) with suitable saccharides or saccharide derivatives (as recognition units) are described. Their production is carried out by the recognition units being reacted with suitable linkers, and the compounds that are produced are conjugated to the effectors. The pharmaceutical use of the conjugates for treating proliferative or angiogenesis-associated processes is described.

In recent decades, a series of highly effective new chemotherapy agents for the therapy of tumors was developed. Despite all of these efforts, the treatment options and the therapeutic window are limited by the high intrinsic toxicity of these pharmaceutical agents.

Only a small portion of the amount of substance administered reaches the tumor (Anderson et al., Clin Pharmacokinet 27, 191-201, 1994; Thorpe et al., Breast Canc Res Treat 36, 237-251, 1995), while the maximum amount of substance is taken up by healthy tissue and thus is responsible for many of the undesirable side effects.

For this reason, the selective release of systemically administered chemotherapy agents at the target site always represents a scientific challenge. More recent developments aim at, for example, detoxifying cytostatic agents by conversion into a prodrug form and cleaving the non-toxic prodrug only when reaching the tumor by tumor-associated enzymes. A validation of this concept could be achieved by Bosslet (Bosslet et al., Canc Res 58, 1195-1201, 1998) in the example of a non-toxic prodrug, based on doxorubicin, which was chemically linked to glucuronic acid. In this case, the finding that an elevated lysosomal β-D-glucuronidase activity is observed in the necrotic areas of many tumors was used.

On the one hand, the relatively low cytotoxicity of the chemotherapy agent doxorubicin that was used and that required a high dosage of the prodrug proved disadvantageous, and on the other hand, the relatively quick development of resistance against doxorubicin itself proved disadvantageous.

The new structural class of the epothilones and analogs thereof primarily offers a possibility of avoiding these drawbacks. Most natural or synthetically modified compounds from their structural class exert their full antiproliferative activity against the most varied tumor cells that are resistant to other chemotherapy agents. The active strength relative to these cells can be up to 10,000× greater, compared to chemotherapy agents that are used in clinical practice, such as, for example, taxol, doxorubicin, cis-platinum or camptothecin.

Within the scope of this invention, surprisingly enough, a possibility has now been found to link the chemically very sensitive highly-functionalized active ingredient class of the epothilones and analogs thereof with a recognition unit that contains a saccharide or a saccharide derivative via different linkers to various positions of the active ingredient.

The object of this invention is thus based on, i.a.,

-   -   1. Finding a method to link highly active active ingredients         from the structural class of the epothilones and epothilone         derivatives with suitable recognition units via linkers, whereby         the resulting conjugates are adequately stable both chemically         and metabolically for a development of pharmaceutical agents and         are superior to the underlying epothilones or epothilone         derivatives with respect to their therapeutic range, their         selectivity of action and/or undesirable toxic side effects         and/or their active strength;     -   2. Synthesizing suitable linker-recognition units;     -   3. Developing a method to link these linker-recognition units         with epothilones to conjugates.

This invention correspondingly comprises conjugates of general formula I

with the condition that at least one substituent L¹, L² or L⁴ represents a linker-recognition unit of general formula (III);

-   -   the linker-recognition unit of general formula (III) has the         following structure,         in which     -   R^(22a), R^(22b), independently of one another, can represent         hydrogen, C₁-C₂₀ alkyl, C₁-C₂₀ acyl, C₁-C₂₀ acyloxy, aryl,         aralkyl, hydroxy, alkoxy, CO₂H, CO₂alkyl, halogen, CN, NO₂, NH₂,         or N₃,     -   U can represent —C(═O)NR²³—, —C(═S)NR²³—, —C(═O)NR²³—CH₂—,         —C(═S)NR²³—CH₂—, —C(═O)O—, —C(═S)O—, —C(═O)O—CH₂—, —C(═S)O—CH₂—,     -   R²³ can represent hydrogen or C₁-C₁₀ alkyl, and EG is a         recognition unit of general formula IV,         in which     -   R²⁴ can represent a group CH₂OPG⁴ or a group CO₂R²⁶,     -   PG¹, PG², PG³, and PG⁴, independently of one another, can         represent hydrogen or a protective group PG,     -   R²⁶ can represent hydrogen, C₁-C₂₀ alkyl, C₁-C₂₀ alkenyl, C₄-C₇         cycloalkyl, which can contain an oxygen atom, aryl, aralkyl,         tris(C₁-C₂₀ alkyl)silyl, bis(C₁-C₂₀ alkyl)-arylsilyl, (C₁-C₂₀         alkyl)-diarylsilyl, or tris(aralkyl)-silyl,     -   PG^(X), PG^(Y), and PG^(Z) can represent a protective group PG,         as a uniform isomer or a mixture of different isomers and/or as         a pharmaceutically acceptable salt thereof.

According to this invention, the above-mentioned conjugates can comprise one or more recognition units; in this case, the recognition units that are related to a conjugate can be identical or different. It is preferred that the recognition units of a conjugate be identical.

The compounds of general formula I can be used in the form of their α-, β- or γ-cyclodextrin clathrates or their substituted α-, β- or γ-cyclodextrin clathrates or in the form of liposomal or PEGylated compositions.

The conjugates according to the invention are preferably used for the treatment of diseases that are linked to proliferative processes. For example, the therapy of widely varying tumors, the therapy of inflammatory and/or neurodegenerative diseases, such as multiple sclerosis or Alzheimer's disease, the therapy of angiogenesis-associated diseases, such as the growth of solid tumors, rheumatoid arthritis or diseases of the ocular fundus can be mentioned.

Especially preferred is the use of the conjugates according to the invention for the treatment of primary tumors and/or metastases that are not operatively accessible, either as monotherapy or in combination with substances that increasingly trigger cell death (apoptosis) and necrosis, so that when cells decompose, it results in an elevated release of normally intracellular, lysosomal enzymes, such as, e.g., glucuronidase, which results in a stronger reaction of the conjugates according to the invention. For example, in this connection, substances that are used for the so-called “vascular targeting” can be mentioned. These substances result in destruction in particular of the tumor endothelium, which subsequently results in an increased necrosis of the tumor because of the deficient nutrient supply. For example, L19 constructs, such as, for example, the EDB fibronectin or combrestatin A4-prodrugs, can be mentioned here.

The invention also relates to the use of a linker-recognition unit of general formula III¹, III² or III³ in one of the processes according to the invention for the production of an effector-recognition unit conjugate as described above.

The invention also relates to the conjugates according to the invention that contain effectors, linkers and recognition units for use as medications or for the production of a medication or a pharmaceutical composition.

The invention also relates to the use of the conjugates according to the invention for the production of medications for the treatment of diseases that are linked to proliferative processes, such as tumors, inflammatory and/or neurodegenerative diseases, multiple sclerosis, Alzheimer's disease, or for the treatment of angiogenesis-associated diseases, such as the growth of solid tumors, rheumatoid arthritis, or diseases of the ocular fundus.

The invention also relates to the use of the conjugates according to the invention for the production of medications for the treatment of primary tumors and/or metastases that are not operatively accessible, either as monotherapy or in combination with substances that increasingly trigger cell death (apoptosis) and necrosis, so that when tumor cells decompose, it results in an elevated release of normally intracellular, lysosomal enzymes, such as, e.g., glucuronidase, which results in a stronger reaction of the above-mentioned conjugates.

Treatment or administration in combination with the above-mentioned substances in this case comprises the simultaneous (both in the mixture and in separate doses) but also the respectively separate administration of the individual components of the combination, for example an alternating administration, as well as administration schemes, in which one component is given as a long-term medication, and the other component is administered in addition at regular or irregular intervals for shorter periods. In this case, the components of the combination can be fed via the same or via different administration paths. In the above-mentioned administrations in combination are preferably those in which the components of the combination achieve an additive action; especially preferred are those administration schemes in which a synergistic action is set.

With respect to a combination administration with the conjugates according to the invention, for example, substances can be mentioned that are used for the so-called “vascular targeting.” These substances result in destruction especially of tumor endothelium, which subsequently results in an elevated necrosis of the tumor because of the deficient supply of nutrients. For example, L19 constructs, such as, for example the EDB-fibronectin or combrestatin A4-prodrugs, can be mentioned here.

Without further elaboration, it is believed that one skilled in the art can, using the preceding description, utilize the present invention to its fullest extent. The following preferred specific embodiments are, therefore, to be construed as merely illustrative, and not limitative of the remainder of the disclosure in any way whatsoever.

In the foregoing and in the following examples, all temperatures are set forth uncorrected in degrees Celsius and, all parts and percentages are by weight, unless otherwise indicated.
